J. DE LONG. INSULATING MATERIAL AND PROCESS OF MANUFACTURING SAME.

UNETED JULIUS DE LONG, OF LAKE MAHOPAC, NEW YORK.
INSULATING MATERIAL AND PROCESS OF MANUFACTURING SAME.
Application filed September 29, 1922. Serial No. 591,362.
To all "LU/LOYIL- it may concur/i:
lie it known that I, Junius DE LONG, a citizen of the United States, residing at Lake Mahopac, in the county of Putnam, State of New York, have invented new and useful Improvements in Insulating Mate rials and Processes of Manufacturing Same, of which the following is a specification.
I My invention relates to improvements in insulating material which are particularly adapted for use in insulating railroad cars, buildings and other structures, and in the process of manufacturing the same; and the other objects of my invention are to produce a new insulating material which can be cheaply and economically manufactured and which will be fireproof in its character.
Reference is hereby made to the following pending applications by the applicant relating to the same or kindred subject matter, namely: Serial No. 432,649, Serial No. 517 923 and Serial No. 556,579.
Figure 1 is a perspective view of my insulating material with the layers of the material used partly broken away. Fig. 2 is an enlarged sectional view on the line w a: of Figure 1. In the drawings, 1 indicates the woven fabric; 2 the bats of asbestos fibre, and 3 the covering of asbestos paper.
Heretofore, fireproof insulating material has been made from asbestos fibre, but in this type of insulating material the fibres were always secured together by glue or other adhesive material, which tended to close and fill the air spaces between the fibres and thereby greatly decrease the insulating value of the insulating material.
Material so formed is liable to disintegrate and fall apart when wet and therefore is undesirable for many purposes for which insulating material is used.
I have found that I can make a strong, durable and substantially fireproof insulating material by the following process:
I run asbestos fibre through a picker until it has been finely divided and then form the asbestos fibre into a hat by running it through a carding machine. I lay a bat so formed upon a strip of fireproofed burlap or other suitable, non-inflammable woven fabric possessing the desired strength, and run the bat and burlap through a needle punching loom, the needles of such loom forcing the finely divided asbestos fibre through the woven fabric and interlocking the fibres of asbestos with each other and thereby firmly securing the bat to the woven fabric, the fibres being of such small diameter that they will not be broken by this step in my process. When this operation is completed I turn the product over and place another similarly formed bat upon the exposed surface of the woven fabric and again run the material through a punching needle loom, with the result that the fibres of asbestos in the upper bat are interlocked and the fibres of the upper bat are driven through the woven fabric and more or less interlocked with the asbestos fibres on the opposite side and with the woven fabric.
This produces a strong, durable felt which is a better nonconductor of heat .than the material heretofore used, and is at the same time essentially fireproof. lVhere burlap is used I treat the burlap with a solution which renders it flame proof. Where a rigid material is required I apply adhesive material to the surface of asbestos paper which I apply under pressure to one or both of the outer surfaces of the felt formed as above stated. Where asbestos is so applied and particularly where it is applied to both sides of the felt, the insulating value is increased because of the dead air trapped between the sheets of asbestos paper. here asbestos paper is applied to both sides of the felt the finished product possesses sufiicient rigidity and strength to be easily handled and applied.
Having described my invention, I claim:
1. The process of manufacturing insulating material which consists of finely dividing asbestos fibre by running it through a picker;
second, running the finely divided asbestos fibre through a carding machine and forming it into a bat; third, laying the bat so formed upon a strip of woven fabric and running the bat and fabric through a punching needle loom; fourth, placing a similarly formed hat of asbestos fibre on the exposed surface of the woven fabric and again running the thus assembled bats and woven fabric through a punching needle loom; and fifth, applying adhesive material to the surface of asbestos paper and applying such paper to the outer surfaces of the felt so formed.
2. The process of manufacturing insulating material which consists of finely dividing asbestos fibre by running it through a picker; second, running the finely divided asbestos fibre through a carding machine and forming it into a bat; third, laying the bat so formed upon a strip of non-inflammable woven fabric and running the bat and fabric through a punching needle loom; fourth. placing a similarly formed bat of asbestos fibre on the exposed surface of the woven fabric and again running: the thus assembled bats and woven fabric through a punching needle loom; and fifth, applying adhesive material to the surface of asbestos paper and applying such paper to the outer surfaces of the felt so formed.
3. An insulating material comprising in combination woven fabric, bats of finely divided asbestos fibre on each side of such woven fabric. the asbestos fibres in each bat being interlocked with each other. with the woven fabric and with the asbestos fibres on the opposite side of such woven fabric.
4. An insulating material comprising in combination non-inflammable woven fabric. bats offinely divided asbestos fibre on each side of such non-inflammable woven fabric, the asbestos fibres in each bat being interlocked with each other, with the noninfla-mmable Woven fabric and with the asbestos lib-res on the opposite side of such non-in flammable woven fabric.
An insulating material comprising in combination woven fabric bats of finely divided asbestos fibre on each side of such woven fabric, the asbestos fibres in each bat being interlocked with each other, with the woven fabric, with the asbestos fibres on the opposite side of such woven. fabric and asbestos covering on each side thereof and secured thereto by adhesive material.
6. An insulating material comprising in combination non-inflammable woven fabric. bats of finely divided asbestos fibre on each side of such non-inflammable woven fabric, the asbestos fibres in each bat being interlocked with each other, with the non-inflammable Woven fabric, with the asbestos fibres on the opposite side of such non-inflammable Woven fabric and asbestos covering on each side thereof and secured thereto by adhesive material.
